A procedure has been developed that through the use of the Leitz Texture Analyzer System (TAS) makes it possible to automatically obtain JK-inclusion ratings consonant with those obtained manually by ASTM E45, Methods A and D, which provide qualitative and quantitative data, respectively. In the new procedure, sulfide inclusions are detected by gray-level differences because image analysis techniques cannot distinguish between type-A sulfides and type-C silicates on the basis of morphological differences alone. Next, the stringered and globular oxides are seperated. Type-B and Type-C stringered oxides are seperated on the basis of the length of the largest oxides in a stringer. After each inclusion type has been isolated, the required measurement is made and the severity is calculated. For each type, the inclusions are further seperated according to thickness. Reproducibility of ratings with the new procedure is quite good, and the results obtained are in good agreement with those done manually.
